To all whom 'it 'may concern:

Be it known that We, QUJNTIN MAmNo, engineer, residing at 2S Montague street,

RussellSquare; NV. C., in the county of Lone don, England, and EDWARD WILLIAM BAR,- ToN-WRIGHT, engineer, residing at l Alberi. .marle street, Piccadilly, l/V., in the county of London,'England, both subjects ofthe King ofyGreat Britain and Ireland, have invented certain new and useful Improvements in the Construction of Electric Accumulators, of:

which the following is a specification.

This invention hasforits object the con! struction of electric accumulators and is especially applicable to accumulator bat? teries where plates and fiber-sof treated wood in connection with the same are employed.v According to the said invention each posi- 'tive and negative plate of the accumulator is formed ol a sheet oi lead provided. with a termina] and having its faces roughene'd or serrated, the said faces or surfaces of the plates being recessed or formed with raised edges to provide receptacles in which the active material is spread. and compressed. Each plate is formedfwith one or more holes-'in alinement with each other and the edges of which are likewise raised. vIn order to insure the escape of the expanded gas whichmay havel been produced, an Archimedean or similar screw rod is passed through the hole or holes in the plates, the samebemg formed of wood or other non-conductor. The positive and negative plates are arranged horizontally and alternately one .above the other in such manner that on one side of the element the terminals of all the positive plates are situated, andupon the opposite side theterminals of the negative plates are situated.

Each positive and lnegative plate is sepa` rated by a plate of wood of about one millimeter in thickness, which wood is specially treated, and is of similar dimensions to the lead plate and perforated with an equal number of holes. The two surfaces of each Wooden plate are lined with a layer of wood iibers, previously specially treated, so that f the active material comes into contact only be formed with cross ridges or ri with the fibers, each lead plate being situated between two wooden lates covered with such fibers, or instead o using the said fibers the surfaces of the wooden lates may lis-thus allowing s aces between the lead plates and the Woo en plates for the passage or flow of the active material or existing liquid.

-drawings in which from the faces.

The terminalsof the plates of the same nature are connectedwith each other by a` .vertlcal leaden rod or plate to which they are soldered, the said -rods orplates being A provided with two rojectionsat thetop and bottom between w ich are` supported ebon-v ite plates for insuring the tightness, strength f and compactness vof the element or series'` f of plates formirighthe accumulator. -xAnd c in order to more lully describe. our said inventlon reference 1s had to the accompanying Fig.- 2 is alongitudinal section. of one of the lead plates, and Fig. 3 is a plan of the saine. Fig. 4 is a sectional elevation ofthe upper' `portion of the accumulator. Fig. 5 is angelevation in .perspective of a .complete accu- T mulatorj Fig. 6-is a plan of one of the; wooden plates, and Fig. 7 is a longitudinal section of the same.

been produced, to escape, and it also-carries away or receives any of the active material which may have passed 'down-theholef from 105 any of the plates, the said screw being capable of removal for cleaning purposes or the like.

lt are the-plates offtreated wood erforated with a hole 7i in line with the ho e f in the l10` plates and formed on one face with ribs h2. The plates h are placed between each positivev and negative plate, the ribbed faces' vcontact only with said ibers.

, 'The terminals of the positive plates and the terminalsof the negative plates are connected to each other respectively by the vertical leaden rod or plate i on one side of the accumulator andfthe rod Ior plate 7c' on the other side of the same; For this pure pose the terminals c pass respectivelyT slots 'i' formed inthe rods or plates i t and cwtomwbich the said terminals are sol- 'The upper and lower end s of therods or platesi and k are provided with two projections or flanges l between which are held and an eboniteplate m at the bottoni of the accumulator for insuring the tightness,

strength and compactness of the same. "-'jLBy means of our invention plates of any `supperted an ebonite plate m at the top and desired shape or size may beans min the construction of accumulator htteries owing to the horizontal position of the plates.

Having now fully described the nature of our said invention, whatwe claim and desire to secure by Letters Patent isz,-v

-1n electric accumulators having the positive and negative plates supported horizontally and alternately one abovethe other,'the

combination therewith of separating boards' of specially treated/wood placed between the saidplates and lined on each side with a layer of speciallyT- treated wood iibers', a hole or holes, formed in each -plate `and board in line with each other, a raised rim forming the edge of each hole so as to provide a continuous passage or tube `running vertically through the said plates. and boards, and a vertical screw-threaded rod. iitted within andpassing through each of the said passages or tubes for effecting the escape of the expanded gases, substantially as described.

In witness whereof we have hereunto set ourhands in the presence of two witnesses.
